The roles of selenium and Polydeoxyribonucleotide (PDRN) were investigated in an experimental model of varicocele, with particular regard to the role of NLRP3 inflammasome. Male rats underwent sham operation and were daily administered with vehicle, seleno-L-methionine (Se), PDRN, and with the association Se-PDRN. Another group of rats were operated for varicocele. After twenty-eight days, sham and varicocele rats were sacrificed and both testes were weighted and analyzed. All the other rats were challenged for one month with the same compounds. In varicocele animals, lower testosterone levels, testes weight, NLRP3 inflammasome, IL-1\u03b2 and caspase-1 increased gene expression were demonstrated. TUNEL assay showed an increased number of apoptotic cells. Structural and ultrastructural damage to testes was also shown. PDRN alone significantly improved all considered parameters more than Se. The Se-PDRN association significantly improved all morphological parameters, significantly increased testosterone levels, and reduced NLRP3 inflammasome, caspase-1 and IL-1\u03b2 expression and TUNEL-positive cell numbers. Our results suggest that NLRP3 inflammasome can be considered an interesting target in varicocele and that Se-PDRN may be a new medical approach in support to surgery.<\/jats:p>","DOI":"10.3390\/ijms22031319","type":"journal-article","created":{"date-parts":[[2021,1,28]],"date-time":"2021-01-28T11:54:53Z","timestamp":1611834893000},"page":"1319","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["NLRP3 Inflammasome: A New Pharmacological Target for Reducing Testicular Damage Associated with Varicocele"],"prefix":"10.3390","volume":"22","author":[{"given":"Pietro","family":"Antonuccio","sequence":"first","affiliation":[{"name":"Department of Human Pathology of Adult and Childhood \u201cGaetano Barresi\u201d, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio Girolamo","family":"Micali","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Dental, Morphological and Functional Imaging Sciences, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmelo","family":"Romeo","sequence":"additional","affiliation":[{"name":"Department of Human Pathology of Adult and Childhood \u201cGaetano Barresi\u201d, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose","family":"Freni","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Dental, Morphological and Functional Imaging Sciences, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3226-8522","authenticated-orcid":false,"given":"Giovanna","family":"Vermiglio","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Dental, Morphological and Functional Imaging Sciences, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1651-1409","authenticated-orcid":false,"given":"Domenico","family":"Puzzolo","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Dental, Morphological and Functional Imaging Sciences, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8868-0762","authenticated-orcid":false,"given":"Francesco","family":"Squadrito","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natasha","family":"Irrera","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8254-177X","authenticated-orcid":false,"given":"Herbert R.","family":"Marini","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosa Alba","family":"Rana","sequence":"additional","affiliation":[{"name":"Department of Medicine and Aging Sciences, University G. d\u2019Annunzio, Chieti and Pescara, 66100 Chieti, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4187-2265","authenticated-orcid":false,"given":"Giovanni","family":"Pallio","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Letteria","family":"Minutoli","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"186","DOI":"10.4103\/1008-682X.170441","article-title":"Novel insights into the pathophysiology of varicocele and its association with reactive oxygen species and sperm DNA fragmentation","volume":"18","author":"Cho","year":"2016","journal-title":"Asian J.
